D-Link xStack Switch Series: Meeting the Need at the Edge of the Network 12
D-Link Systems, Inc.
October 2004
Jumbo frame support for larger file applications
Jumbo frame support of up to 9,216 bytes is supported, making the xStack Series ideal switches
for new applications requiring large frames such as storage and graphic/video applications.
Network data will stream more efficiently and processing load can be reduced dramatically.
Rate Limiting
The central flow control rate limiting feature in the xStack Series adds a valuable tool for
bandwidth management on ingress traffic. Similar to an Access Control List, the rate limiting
feature inspects incoming packets headers to allocate a predefined amount of bandwidth for that
traffic flow. If the flow exceeds the assigned bandwidth, excess packets are either dropped or
modified by resetting their DiffServ code point. Rate limits can be configured from 1 Mbps in 1
Mbps increments up to full line rate. Rate limiting is an excellent method of managing and
prioritizing the total traffic coming into a switch and it also enables control of the amount of
bandwidth any port, user, or application is allowed to consume.
Centralized and Simplified Configuration
D-Link’s xStack Series simplifies and centralizes your network management tasks, as multiple
switches can be configured, monitored and maintained with one single IP address from any
workstation running a Web browser. The stack is managed as a single entity, and all stacked
units are identified by a single IP address. A simple yet powerful Web-based interface allows
you to perform most comprehensive management and configuration tasks, eliminating the need
for you to install expensive, complex SNMP network management software.
Redundant Power System
The xStack Series offers a Redundant Power System, which supports multiple xStack switches
all with full power simultaneously. This power system provides 1-for-1 power back-up for every
xStack unit connected. No more worrying about inadequate power if more than a single switch
fails; the External Power System provides full redundant power for every xStack switch. The
Redundant Power System automatically senses when the internal power supply has failed and
immediately provides redundant power to the switch, preventing any loss of data.
Removable Flash Memory System
The innovative removable flash memory system of the DGS-3324SRi dramatically simplifies
complex deployments, upgrades, backups, and replacement sparing. Save your configuration file
on any standard flash memory card then eject the flash memory card for easy transportation.
Cluster Network Management Feature
The xStack Series also supports D-Link’s SIM (Single IP Management) Clustering Technology
software. By utilizing SIM Clustering Technology, up to thirty-two D-Link SIM-capable
switches—xStack or non-xStack switches—can be stacked logically and centrally managed
through a single IP address. SIM Clustering Technology is not limited to the xStack Series, any
physical location, or any specific stacking cables. Any D-Link switch that supports SIM
Clustering Technology can become a member of a SIM cluster or virtual stack. SIM members
